Abstract
One of the most important variables for alcohol use in adolescence is the friends’ deviant behaviour. In addition, personality has also been consistently associated to alcohol use at this stage. The aim of the present study was to examine the direct, mediation and moderation effects of these two variables on adolescents’ alcohol consumption. Four hundred and ten participants (58% females) completed the Junior Spanish version of the NEO-PI-R (JS NEO), the Deviant Peers Scale (DPS) and the Alcohol Intake Scale (AIS). OLS regression analyses showed simple main effects of Extraversion, Deviant Peers and, importantly, and interaction between low Conscientiousness and Deviant Peers in explaining alcohol use. SEM analyses also indicated that low Agreeableness was indirectly associated to alcohol use through the affiliation with deviant peers. In conclusion, there seem to be both mediator and moderator effects between different personality traits and friends’ deviant behaviour on alcohol consumption in adolescence.
